What is formdata-node?

The formdata-node package is a Node.js module that allows you to create, manipulate, and encode multipart/form-data streams. It can be used to submit forms and upload files via HTTP requests in a way that is compatible with browser FormData API.

What are formdata-node's main functionalities?

Creating FormData

This feature allows you to create a new FormData instance and append fields to it, similar to how you would in a browser environment.

const { FormData } = require('formdata-node');
const formData = new FormData();
formData.append('key', 'value');

Appending Files

This feature enables appending files to the FormData instance, which can then be used to upload files to a server.

const { FormData, fileFromPath } = require('formdata-node');
const formData = new FormData();
formData.append('file', fileFromPath('./path/to/file.txt'));

Retrieving FormData Content

This feature allows you to iterate over the entries in the FormData object, enabling you to access the keys and values that have been appended.

const { FormData } = require('formdata-node');
const formData = new FormData();
formData.append('key', 'value');
for (const [key, value] of formData) {
  console.log(key, value);
}

Encoding FormData

This feature is used to encode the FormData into a Blob, which can then be used to send the data over an HTTP request.

const { FormData, formDataToBlob } = require('formdata-node');
const formData = new FormData();
formData.append('key', 'value');
const blob = formDataToBlob(formData);
